Introduction

Now 3D visualization is a fast developing technology. Autostereoscopic
glasses-free 3D monitors are already available. But video materials for
them are still rare. Most of this video is rendered. 3D video creation
is expensive and complicated task, because glasses-free 3D displays
require several views of the same scene (usually 8-9 views). Stereo
video capture is much easier. Stereo films become more and more popular.
Our lab have developed stereo to multiview video conversion algorithm
for glasses-free autostereoscopic 3D displays. This algorithm makes 3D
video creation problem less complicated.

Work description

It is necessary to generate intermediate views to convert stereo to
multiview intermediate.

We have developed conversion algorithm and processed several
professionally captured stereo videos. We also researched 3D video
capturing (more about MSU 3D Video
Capture).

Intermediate views generation doesn’t use depth map construction and
semitransparent objects processing is correct. We also work on depth and
disparity map generation. It can be used in monoscopic to 3D video
conversion.

Our stereo video converting doesn’t need iterative processes and it is
suite for stream processing. Real-time realization is possible. We also
work on GPU version of conversion for more acceleration.

How to view 3D video

To view 3D images you need autostereoscopic monitor and specialized
player. Depending on how many views does your monitor support you should
download 5-view or 9-view video. View order is also important. You
should choose view order (from left to right OR from right to left)
supported by your player.

9 view alignment:

Conversion output format can be also specified to be a sequence of
numbered views or other appropriate way.
